Objective: Severe, late functional tricuspid regurgitation is characterized by annulus dilation, right ventricular enlargement, and papillary muscle displacement with leaflet tethering. However, the early stages of mild tricuspid regurgitation and its progression are poorly understood. This study examined structural heart changes in mild, early tricuspid regurgitation.
Methods: Sequential patients undergoing cardiac computed tomography and transthoracic echocardiography with tricuspid regurgitation were identified and evaluated. The tricuspid annulus area and chamber volumes were measured by computed tomography angiography and categorized by tricuspid regurgitation severity.
Results: Patients (n = 622) were divided into 3 groups by tricuspid regurgitation severity: no/trace (n = 386), mild (n = 178), and moderate/severe tricuspid regurgitation (n = 58). Annulus area was highly dependent on and proportional to regurgitation severity and correlated with both right/left atrial enlargement. Annulus area most strongly correlated with right and left atrial volume, and the annulus shape changed from elliptical to circular in moderate/severe tricuspid regurgitation. Mild tricuspid regurgitation was associated with less right/left atrial enlargement than significant tricuspid regurgitation, normal right ventricular size, and annular dilation. Significant tricuspid regurgitation was associated with annular dilation, circularization, and right ventricular enlargement. Mild and significant tricuspid regurgitation were differentiated by annulus area and indexed right ventricular volume.
Conclusions: Tricuspid annular dilation and right/left atrial enlargement comprise early events in mild functional tricuspid regurgitation. Atrial enlargement occurs before right ventricular dilation, which occurs late, when tricuspid regurgitation is severe. Atrial volume and tricuspid annular dilation are early and sensitive indicators of tricuspid regurgitation significance.

Background: Significant tricuspid regurgitation (TR) is associated with increased morbidity and mortality. The development of transcatheter valve repair therapies has opened a wide range of opportunities for treatment of patients with high surgical risk. Real-world data might improve patient selection and outcome.

Background: Valvular heart disease (VHD) is a major focus of cardiovascular medicine, but limited data are available for racial and ethnic minorities. The aim was to assess the burden and clinical correlates of VHD in a highly diverse area of the United States.
Methods And Results: Individuals with echocardiographic diagnosis of native VHD between January 2010 and December 2019 at a quaternary care health system of the Bronx (New York, USA) were included.

Background: Population-based analyses may reduce uncertainty related to referral bias and/or incomplete follow-up.
Objectives: This study analyzed long-term mortality and durability of mitral valve repair in a geographically defined population with clinical and echocardiographic follow-up.
Methods: We used the Rochester Epidemiology Project to identify 153 Olmsted County patients who underwent mitral valve repair for degenerative regurgitation from 1993 to 2018.
Background: Light-chain cardiac amyloidosis (AL-CA) is associated with structural and functional changes in the left atrium and left ventricle. This study aims to assess the value of the left atrioventricular coupling index (LACI) assessed by three-dimensional echocardiography (3DE) for predicting primary outcome in AL-CA.
Methods: Participants with biopsy-confirmed AL-CA from April 2022 to February 2024 were prospectively analysed.
